' Patented April 28, i908.

-To all whom it may concern.'

Be it known that we, CHARLES WILLIAM PHIPPs, trading as PHIPPs & SON,merchants and manufacturers, and WILLIAM JOHN STEELE, engineer, bothsubjects of the King of Great Britain, citizens of Northampton, England,residing at Guildhall Road, Northampton, England, have invented new andvuseful Improvements in Cementing Apparatus, of which the following isaf speciiication.

This invention relates to apparatus for containing cement, adhesive orthe like and is particularly, though not exclusively, applicable to thetype of cementing machine employed in coating with cement the edges ofmaterial, such for example as sections of the uppers of boots and shoesto unitel them temporarily preparatory to their being permanentlyconnected together in a sewing machine. Machines of this character haveheretofore comprised in their construction a vessel or receptacle tocontain the main supply or stock of cement, a closable opening throughwhich the vessel is iilled, a trough having a duct communicating withthe main receptacle and for containing a small quantity of the cementfor immediatefuse and a shutter to close the trough or its duct so thatthe cement, which may be of a highly inflammable nature, may not remainexposed when not in actual use.

The present invention relates to an improvend construction of machinecomprising a main vessel or stock receptacle, a feed opening or inlettherein, a slidable door thereto having a locking device, such forexample as a spring controlled pin or bolt and lever, to lock the saiddoor in its closed position and secure the cement against exposure tothe atmosphere, and means, such for example as a cam lever, to withdrawor slide the door or lid away from the feed inlet of the vessel orcement pot.

The invention also comprises a valve which automatically closes andopens the duct leading from the receptacle to vthe vtrough synchronouslywith the opening and closing respectively of the. feed opening. Whilethe valve and duct are open the cement will be maintained at a uniformheight in the trough, but when the sliding door of the feed opening iswithdrawn it is advisable to close the said duct to prevent a rush 'ofcement into the trough and an overiiow of the latter. When however it isonly desired to replenish the trough by allowing cement to flow throughthe duct into the latter, or to cut off the communication between thetrough and the main supply in the receptacle,

the locking device of the sliding door is not released, and the camlever is given a sufficient amount of movement to operate the valve rodand valve to open or close the said duct. The cement may be taken fromthis trough by a brush and the operator may paint or coat the edges ofthe upper sections with it in the well understood mamier. In orderhowever to effect this operation i. e. coating the edge of the uppersection, mechanically and automatically, as far as we are aware for thefirst time, a roller may be revolubly located and dip in this trough sothat when the edge of the upper section is passed thereover it will takeup the cement from the surface of the roller and become coated therebyand'at the same time will by frictional contact simultaneously rotatethe roller in the trough so as to bring a fresh surface of the roller tothe next upper'section.

A ressure device referably in the form of a rol er may be emp oyed topress the upper section on to the coatin roller. Such pressure roller isnormally ield out of contact with the coating roller by a spring orequivalent means so as to keep it clean and prevent it coating the oposite edge of the upper section as it would o if both rollers were insurface contact. The coating roller may also if desired be ositivelydriven through the medium of suitable mechanism such for example as gearwheels, a driving shaft and belt pulley thereon.

When it is desired to coat both sides or edges of the uppersection orother fabric with cement the pressure roller and the coating roller areallowed to be permanently in1 surface contact.

The invention will be further described in detail and reference made tothe accompanying drawings wherein Figure 1 is a front elevation of acementing a paratus constructed in accordance with t iis invention. Fig.2 is aK longitudinal section of the apparatus and Fig. 3 is a plan ofsame. Figsf and 5 are plans of the main parts of the apparatus and showthe slidable door in its closed and open positions respectively.

Like reference characters are employed to designate the same parts inall the figures.

In a machine'constructed according to the present invention 1 representsa main vessel or stock receptacle furnished at its up er end with aslidable lid or door 2 having a ocking 5 device to lock it in its closedposition. A

convenient construction of locking device comprises a spring controlledbolt 3 carried in a hxed bracket it and operated vertically therein tounlock the lid by depressing one end of a lever 5 pivoted to saidbracket as shown in Figs. 2 and rllhe stock vessel 1 has a feed inlet orilling opening (i therein and when the latter is covered and closed bythe slidable doei' 2, as shown in Figs. 1 to 4;,

the locking bolt 3 under the influence of its s ring bears with pressureupon and forces tlie said door 2 down air-tightly upon a joint ring 7 ofrubber or equivalent material arranged around the feed inlet and thussecures the cement against exposure to the atmosphere.

rllhe slidable door or lid 2 may be withdrawn from over the feed opening6 of the stock vessel for iilling purposes by means of `a cam lever Sthe latter (after the bolt 3 is lifted fioni the doei' 2 by depressingthe free end of the lever 5), slides the said door to the withdrawnposition shown in Fig. 5.

The front lower portion of the stock receptacle 1 is furnished with atrough 9 and a -duct 10 communicates between the said trough and theinterior of the stock receptacle, to permit cement to flow into thetrough. A convenient construction of valve for con- `trolling the flowof the cement through the nected to the cam lever 8 and is operatedthereby. The lower end of the rod 11 is provided with a diainetricalhole forming a valve 12 so arranged that it may be moved into ahneinentor register with the duct 1() and thereby forni a through passage forthe cement to flow into the trough from the stock vessel, as shown inFigs. 2 and 3; upon the said rod being partly rotated it will close thesaid duct 10 by bringing a solid or unperforated portion of the rod 11opposite thereto as shown in Figs. 4 and 5, and thus stop the cementfeeding to the trough.

The cam lever 8 is attached. to the valve rod 11 in such a position thatwhen the said lever is moved to withdraw the door and nncover the feedopening 6 the rod will be synchronously turned thereby to the positionto close the duct- 10, as shown in Fig. 5, and vice versa. Thissimultaneous action of opening the door and closing the duct will onlybe necessary when it is desired to re-iill the stock receptacle. Thenhowever it is required to open the valve to replenish the trough 9 only,by allowing cement to flow thereinto through the duct' 10, or to cut offstop pin 14, Figs. 3 to 5, and it will be noticed, by reference to thelast named ligure, that owing to the particular positions of the lever Sand valve or hole 12 on and in the rod 11 it is impossible to open thefeed inlet and door 2 without first closing the duct lt). For thepurpose of mechanically and automatically coating the. edge of a bootupper section or similar goods the machine is furnished with a roller 15revolubly located in the trough Sl so that its lower part constantlydips in the cement. Then the said roller is rotated by the passingthereover of an upper section o1' by positive driving means, ashereinafter described, it will take up the cement and thereby coat thegoods placed in contact therewith.

pressure roller 1o is carried on a. pivotedI lever 17 Fig. l the saidroller being normally held out of contact with the coating roller 1:1 bya spring 1S Figs. 1 & 2%.

The pivoted lever 17 of the pressure roller 1G is connected b v means ofa chain 1t) to a foot pedal or knee lever (not shown) so that wheneither of the latter is actuated it will lower the. pressure roller 1 onto the u ppersection or other work and press it into positive contactwith the coating roller, to receive a coating of cement'. therefrom.'llhe surface of the latter roller may be milled or serrated and thelowering of the. pressure roller 1U by the operators foot or knee leavesboth his hands free to manipulate the work passing between the rollers.

Mechanism may be arranged to positively drive or revolve the coatingroller 15 and this mechanism according to one arrangement may consist ofa driving shaft 2t) actuated by bevel wheels 21 from a belt pulley 22the said i'oller being driven `from the shaft 2() b v intermediate gearwheels 23 Figs. 1 and 2.

Then it is desired to coat each of the two opposite sides or edges ofthe upper section or other fabric with cement the pressure roller 1G andcoating roller 15 are allowed to be permanently in surface contact sothat the cement will be taken up by the coating roller and transferredthereby to the top or pressure roller.

Then no coating or pressure rollers are employed the operator removesthe cement from the trough by a brush and applies it to the material inthe well known manner. Then however the coating roller or rollers is orare employed the cement is allowed to flow continuously through the duct10 into the trough while the machine is 1n use. The most importantfeature however of the invention is the arrangement by which` the valvewhich controls the supply of cement to the trough, and the o ening andclosing of the door over the feed mlet are controller by the same lever8 the latter being so arranged that when moved in one direction (shownby the arrow) to the limit of the cam slot it ro'- tates the rod l1 andremoves the hole 12 therein away from and out of register with said ductso that the valve and duct are closed and the flow of cement to thetrough is stopped. The lever, if its movement is continued Will byressing against the pin on the door 2 slide t e latter along andwithdraw it from over the feed opening 6 to permit of the stock vesselbeing re-filled. It will be obvious therefore from the foregoingdescription7 that the movement of the lever 8 within the limit of theslot in one direction will open the valve and duct so that cement mayflow into and replenish the trough and the movement of the said lever'within the linit of the slot in the opposite direction will and ductare closed the lever slides the door` away from and exposes the feedinlet. The said lever therefore with a limited movement in oppositedirections opens and closes respectively the valve and duct and with afurther and continued movement in the same directions closes the saidvalve and duct and stock receptacle, a .trough communicating therewith,a feed opening to the said receptacle, a door, and a cam lever toactuate the said door to close and open respectively the said feedopening.
